■Verify the accuracy of the default gateway’s IP address (entered in the IP Setup or Easy Setup screen).
■Use the Netopia D-Series’s Ping utility, in the Utilities & Diagnostics screen, and try to ping local and
remote hosts. See “Ping” on page 9-92 for instructions on how to use the Ping utility. If you can
successfully ping hosts using their IP addresses but not their domain names (198.34.7.1 but not
garcia.netopia.com, for example), verify that the DNS server’s IP address is correct and that it is reachable
from the Netopia D-Series (use Ping).
■If you are using filters, check that your filter sets are not blocking the type of connections you are trying to
make.
